CPU Compatibility

I was curious that if I start out with a Pentium 4-M 1.7 GHZ CPU which uses the Intel 845MP chipset, would I be able to use a CPU such as a Pentium M (Socket 478, of course) when the Pentium M needs the 855 chipset series?

I don't know the motherboard, but it's for a Compaq Evo Notebook N800c and the CPU is an Intel® Pentium® M Processor 1.40 GHz . I hope that helps any. All I could find online was that this laptop's mobo had the Intel 845MP chipset in it and I found on Intel's site that Pentium Ms require the 855 chipset. I'm hoping I could get around it; if not there's always ebay :haha:
